Please consider submitting an abstract to the session "GC051 Thresholds in Soil Response to Global Change " at the American Geophysical Union (AGU) 2013 Fall Meeting, December 9-13, 2013, San Francisco CA USA.
GC051. Thresholds in Soil Response to Global Change Submission are open until August 6, 2013. Description: Global change impacts and response are mediated strongly by soils, the core component of the Earth¹s critical zone. The capacity of the soil system to withstand global-scale perturbations (e.g., climate or land use change, spread of invasive species) may depend on non-linear thresholds in soil state and function as these forcing factors increase in extent and severity. This session explores thresholds of change in soil state and function to better understand vulnerability to global change. Studies that focus on non-linear shifts carbon storage and release in soil,novel isotopic fractionation, changes in soil-water interactions to better understand non-linear thresholds in soil condition, water transport and chemistry are encouraged.
